It would be the second one.
4(2x^2 + 5y^2)(2x^2 - 5y^2)
Answer:
32 weeks.
Step-by-step explanation:
Let w represent number of weeks.
We have been given that the new plan will have the office recycling 1 kilogram of paper each week. So kilograms of paper recycled in w weeks would be
.
We are also told that Toby's office had already recycled 7 kilograms. So total kilogram of paper recycled in w weeks would be
.
Since Toby's office has to recycle a total of 39 kilograms of paper, so we will equate 39 with paper recycled in w weeks as:



Therefore, it will take 32 weeks for Toby's office to recycle a total of 39 kilograms of paper.
Answer:
good job.
Step-by-step explanation:
The value of csc theta is 
<h3>How to determine the value</h3>
It is important to note that the ratio for cot is given as;
Cot theta = adjacent/opposite
cosec theta = hypotenuse/opposite
If cot theta = 3/2, then
Adjacent = 3
Opposite = 2
Using Pythagoras theorem, we have
Hypotenuse square = opposite + adjacent square



Cosec theta = 
Thus, the value of csc theta is
